Polymeric media amendment

摘要

A medium for enhancing growth and availability of water and nutrients during plant growth, comprising a synthetic resin and a support material, the resin consisting essentially of a substantially-linear, non-gelling, water-soluble polymer capable of forming a water absorbing network with the support material, such that the polymer is dispersed within the material upon exposure to water and retains and transports water and nutrients for seedling growth. Use of such polyacrylamides benefits growth by retaining water, reducing evaporation loss, improving yields and enhancing nutrient uptake.
